In this version, I added that if any errors occur, you can see them in the console to simplify feedback. If your problem remains, and there are no errors in the [F2] console, then alas, I can't help you in any way, except how you can delete doors by entering the remove forward command.
Thank you so much for going the extra mile. Sincerely appreciate! I just started to record to show you guys what happens and now the doors simply open, so I can actually play the game. HURRAY!!! [v 1.1.1] And a big thumbs up for all involved :o]
Thank you for your time, I hope you enjoy it. By leaving comments and notifying me of similar problems, you help me improve this project. Thanks again and have a nice day!
